Mortenson has just announced its 100th wind energy project and points to the fact that it is working on 11 more projects which amounts to a planned generating capacity of about 1,363 megawatts. According to Mortenson, that amounts to enough electricity to power about 400,000 average homes.

Mortenson’s 100th wind project, the Rolling Hills Wind Farm, is located in southeast Iowa and is said to be one of the largest single-phase wind projects ever to be built in the U.S. Mortenson reports that when the wind farm is completed in December 2011, it will generate 443.9 megawatts of power using 193 Siemens 2.3-megawatt wind turbines. Mortenson says it feels the scale of the project is a good indicator of the “appetite for wind power in the U.S.”
